Iridium is Mirka’s premium paper-backed abrasive for universal sanding. It has a mix of ceramic and aluminum oxide grains on a flexible paper with precision coating that prevents clogging and reduces pilling.
Available in a range of eight grits (80x, 100x, 120x, 150x, 180x, 220x, 240x, 320x), priced per disc.
